Abstract
A method for controlling an image forming apparatus which has a photoreceptor and a writing system to write a latent image on the photoreceptor with plural laser beams. The method includes the steps of: correcting positional deviations among the plural laser beams; conducting at least one of maximum density correction and gradation correction for image forming operation of the image forming apparatus by providing at least one standard density pattern on the photoreceptor with the plural laser beams; and repeating the correcting step of positional deviations among the plurality of laser beam. All of the steps are conducted when the image forming apparatus is in a warm-up state in succession to a turn-on operation thereof.
